BOILER-WASHOUT DEVICE.

SPECIFICATION formingpart of Letters Patent N o. 671,964, dated Apri1'16, 1901.

Application fieled October 4, 1900. Serial No. 31.949. (No model.)

To a/ZZ whom it may concern:

Be it known that I, BENJAMIN F. KEENEY, a citizen of the -United States,'residing at Watertown, in the county of Codington and State of South Dakota, have invented certain new and useful Improvements in Boiler- Washout Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention has for its object to provide an improved boiler-washout device; andto this end it consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout both views.

Figure 1 is a vertical section taken centrally through a horizontal boiler equipped with one of my improved washout devices, some parts being shown in full and others being broken away. Fig. 2 is a horizontal section approximately on the line m2 m2 of Fig. 1, the lues being removedto more clearly show the mechanism below the same.

The numeral 1 indicates an ordinary horizontal boiler having i'lues 2 in the ordinary arrangement and provided at one end with an ordinary manhole-cover 3, held in the ordinary way by yoke 4 and nutted bolt 5.

In my present invention I preferably employ a horizontal catch-trough, which is advisably a separate part, but which may nevertheless be formed integral with or as a part of the bottom of the boiler. This trough in its preferred arrangement is indicated by the numeral 6, and it .is shown as provided at one end with a head 7.

The discharge-pipe 8 works through a stuffare shown as adjustably secured at 15, is provided with pronged heads 16 and 17, that are secured to the supporting-rods 13. The trough 6 is suspended from the rods 13 by cross-bars 18 and by the prongs of the bracket-head 17. A pair of sprockets 19 and 2O are suitably mounted, the former, as shown, having a shaft 21, mounted in the prongs of the head 16, and the latter having a short shaft 22, mounted in the prongs of the head 17, both sprockets being located vertically over the discharge pipe 8. The sprocket-chain 23 runs over the sprockets 19 and 20, and one link thereof is pivotally connected, as shown at 24 in Fig. 1, to the inner end of the discharge-pipe 8. One member of a pair of bevel-gears 25 is secured on the shaft 21 of the sprocket 19. The other member of said gears is secured on the short shaft 26, which is suitably mounted in the prongs of the bracket-head 16 and Works outward through the small stuffing-box 27, which, as shown, is also applied to the manhole cover 3. As shown, the shaft 26 is formed at its outer end with a squaredv shank, to which a detachable hand-crank 28 is adapted to be applied, as shown in Fig. 2.

One of the main objects of my present invention is to provide simple and efficient means whereby the discharge-tube may be moved longitudinally of the boiler with a positive actionin both directions, and this I have accomplished, as is obvious from the foregoing description.

By turning the crank 28 in the one direction or the other the sprocket-chain 23 may be driven in either direction, so as to positively move the open inner end of the dischargetube 8 in either direction longitudinally of the trough 6. Hence the discharge-tube may be given its desired movements whether or not there be steam-pressure in the boiler.

To Wash out the boiler, the valve 10 of the discharge-pipe 8 is open and the said pipe is moved slowly back and forth, as above indicated. Under this movement of the discharge-tube the scraper 12 stirs up the sediment and `causes the same to be carried off through the discharge-tube with the Water.

IOO

Water-level and havinga detachable manholecover, of a discharge-pipe working longitudinally through said manhole-cover and provided at its inner end with a scraper, which discharge-pipe, together with said scraper, is removable with said manhole-cover and through said manhole, substantially as described.

In testimony Whereof I ax my signature in presence of two Witnesses.

BENJAMIN F. KEENEY.
